Got me, looks like a nice bike! Sure it's not sporty, but that's the point. It's a commuter, not something to race in the Tour who cares France.
If it does what you want and you are happy, who cares if it is a $50 bicycle or a $50,000 bicycle. Who cares what some anti department store bike snob thinks. If you ride it and like it that's what counts! I myself am always glad to see someone enjoy a more relaxed style bicycle and not give in to this countries sports bicycle culture.
If you get into rebuilding bicycles often I would check out dutch bike bits (
http://www.dutchbikebits.com/) for parts. They specialize in parts for dutch bikes, but many of those can be used on a standard bicycle.
Good luck and learn to ignore those negative nellies, I have.
